  • the radio bearer release procedure may be initiated by the RNC RRC 1 10 after a predetermined period of time or in response to events such as congestion in the cell 108b the UE 102 is operating in or other network events.
  • An advantage of this arrangement is that, where the UE 102 has had its connection state transitioned by the RNC 104 from a high activity state associated with a data streaming connection to a lower activity state in response to a silent period detected in the data streaming connection, the retention by the UE 102 of the TM RB information for a period of time allows the high activity data connection to be readily re-established once data begins to flow again without the need for a radio bearer setup procedure to be implemented. Consequently, the period of time may be chosen as any suitable period and may be one that is statistically just longer than a longest silent period detected in a data stream that has been communicated over the TM RBs during a sampling period.
  • the UE 102 In order to re-establish the high activity connection (dedicated channel) state for the UE 102 in accordance with the preferred embodiment of the present invention, it is only necessary for the UE 102 to send to the RNC 106 a cell update message 402 as illustrated in figure 6.
  • the sending of this cell update message 402 may be prompted by receipt at the UE 102 of a paging type 1 message 400 from the RNC 106 on the CELL_PCH connection or URA_PCH connection between the UE 102 and the UTRAN 100.
  • the RNC 106 responds to the cell update message 402 with a cell update confirm message 404.
  • this message exchange between the RNC 106 and UE 102 effectively comprises the first part of the known message exchange described with respect to figure 4 and consequently like numerals have been employed in figure 6 to those employed in figure 4. It will, however, be noted that in the arrangement in accordance with the present invention, it is not necessary to perform the radio bearer setup procedure 306, 308 since the UE 102 already has the necessary TM RB information previously established for the dedicated channel connection.
  • the number and size of messages exchanged by the UE 102 and RNC 104 to re-establish the high activity connection is smaller than in the case described with respect to figure 4.
  • less connection re-establishment data is transferred over the air interface 103 which reduces the likelihood of interference with other UEs, reduces the likelihood of signalling errors or signalling collisions and speeds up the transition of the UE 102 to a dedicated channel connection.
  • the UE 102 when transitioning to the CELL FACH state, the UMTS specification requires that all RBs must have a valid mapping to the UMTS RACH and FACH transport channels but this is not possible under the current specification for TM RBs. Consequently, in the arrangement in accordance with the invention, the UE 102 after sending the cell update message 402 and when transitioning to the CELL FACH state is arranged to only check signalling RBs and to delay checking non-signalling RBs until the UE 102 receives the cell update confirm message 404 from the RNC 106. The UE 102 can then perform the necessary checks on non-signalling RBs since the RNC 106 has now had an opportunity to remedy the lack of valid mappings, e.g. by moving the UE 102 to the high activity state, i.e. the CELL_DCH state.

Abstract

L'invention concerne un procédé permettant de maintenir des porteuses radio en mode transparent dans le réseau d'accès radio (RAN) d'un réseau de télécommunications mobile de troisième génération. Ce procédé consiste à gérer les ressources radio attribuées à un équipement utilisateur (UE) dans ledit réseau d'accès radio. Le procédé selon l'invention consiste généralement à communiquer un message provenant d'un contrôleur de ressources radio (RRC) du réseau d'accès radio à l'équipement utilisateur, ledit message étant destiné à donner des consignes à l'équipement utilisateur afin de permettre la transition d'un état de connexion à canal réservé à un état de connexion à activité inférieure, et de stocker dans sa mémoire des informations de porteuse radio (RB) en mode transparent (TM) associées à l'état de connexion à canal réservé. Le stockage d'informations de porteuses radio en mode transparent associées à l'état de connexion à canal réservé permet de reconfigurer l'équipement utilisateur dans un état de connexion à canal réservé sans que le réseau d'accès radio n'ait à mettre en oeuvre une procédure de configuration de porteuses radio.
